Application filed March 26, 1923. Serial No. 627,871.

generally improve and simplify the constructionand operation of machines of this character. I accomplish this object by providing a series of interspaced, superposed, reciprocating knivesv -whereby clean cu t slices of uniformthickness are obtained, and

in conjunction therewith a turret, consist-- ing of a series of interspaced, superposed plates between which the knives operate and in which are formed pockets for the reception of the pineapples to be sliced. I further employ means for intermittently rotating the turret to movethe pineapples from a feeding position to a cuttingposition and finally to a discharge position, and in conjunction therewith I provide means for imartin a reci rocal movement to the knives whenv they engage the pineapples to be sliced. v 7 One form which my invention may assume is exemplified in. the following description and illustrated in the accompanying drawings, in.which Fig. 1 is a front View of the machine, Fig. 2 is a .side elevation ofthe same Fig. 3 is a plan view. .Fig. 4C is, a side elevation of one of. the intermittent motion spiral gears.v

'Fig. 5 is aideveloped detail plan or edge .view thereof.

' Fig. 6 is a side elevation of the continuously rotating spiral driving gear. 1

Fig. 7 .is adeveloped plan'or edge view thereof.

Referring'to the drawings in detail, and

, particularly to Figs. 1, 2 and 3, indicates 1 a main frame in which is supported a centrally disposed vertical shaft 2. Secured on the upper end of the shaft is a turret gen erally indicated at B and arranged above the turret 1s a frame plate 3 on which is supported a receivinghopper 4. Disposed be-.

low the turret is a -second horizontally-post.

tioned frame plate '5 and'supported-by the frame plates '3 and 5 is a pair of opposed guide members 6'between which mounted a vertically disposed cross-head 7, The turret proper consists of a series of interspaced, superposed, annular disks or plates 8, which are secured together by means of bolts 9, and which are provided with hub members 10 to maintain the desired spacing. The cross-head 7 supports a series of superposed knivesor cutting blades 11 (see Figs. 1 and 3) which enter the spaces between the plates of the turret and which serve the function of slicing the'pineapples as willhereinafter be described. The disks are provided with aseries of pockets, such as indicated atl2, which first serve the function .of receiving the pineapples, secondly that of carrying thepineapples andsecuring the same when acted upon by theslicing knives, and third, that of transferring the pineapples when sliced to a discharge opening 13-and a connected chute 14. The turret proper, which; is carried by'the shaft 2, is

intermittently "rotated and this is accom plished by means of a pair of intermittent motion spiral gears generally indicated at 15 and 16. The spiral gear 15 is continuously rotated and is secured upon a shaft 17. Thespiral gear 16 is intermittently rotated is slidably and is securedupon themain shaft 2. The.

gear 16 is in reality nothing more orless than a mutilated spiral gear such as clearly illustrated in Figs.;t and :5. v

Thedriving pinion 15 contains. threeordinary spiral teeth as shown'at 18, in Fig.

7 and has a continuous tooth .as indicated at 19. The gear 15; isflisposed at right anglesto the gear 16 and the tooth-l9 there? fore'enters one or; another of thespaces indic'atedat' 20 formed between theteeth of the gear 16 when thisis at rest,.but rotation is imparted to the gear 16 when the teeth 18 of a pulley25 orthe likeLSQCuredon the V opposite end of shaftfia isja cam .26. and

of the driving pinion engage the same. In

this manner an intermittent movement simn lar'to that obtained by an ordinary Geneva movement is secured.

The shaft 17 carries an ordinary spur gear :22 and- :thisineshes l th a drivingpinion. 23 secured on, a shaft'24, which in. turn is driven from an exterior source by means adapted to be oscillated by the cam'is a lever 27 which is pivotally supported atits upper end to the frame plate 3 as indicated at 28. The cross-headz7 is connected with the oscillating arm 27 through means of a link 29 and the knives'll are therefore' initerm-ittently reciproicated, the reciprocal movement being imparted during the turn ing movement "of the turret or, in other .words, swhen aIi-pineapp'le is 1 "being passed through the 'knives. i'This reciprocal movement.iso'f considerable importance as it prosduces a drawing or sliding-cut which is exceedinglyeficctive and produces uniform sliceswith clean-cut edges and a general improved appearance.

= In actual operation when power is trans- 'mitted to the-pulleyQS, it will be seenthat the shafts 2a and l? will continuously rotate and that fshaftg2- will' intermittently rotate. It will further be'seen thatan intermittent oscillating movement will be transmitted to the lever '27 and. as this is connected to-the cross-head7, which carries the slicing knives, a reciprocal movement will be transmitted thereto. The pineapples to be sliced are deliveredto the hopper 4:

V and drop by gravity into the pockets 12 as =they one by one register therewith during the intermittent rotation of the turret. This intermittent rotation carries the pineapples delivered to the knives 11 and as the knives it registers with the hopper.

are reciprocated during this movement, a drawing or slidin-g out is produced with the result that clean-cut edges are obtained without waste, and further that the result insures slices of uniform thickness and attractive appearance. Thei'nte'rmittent rotation finally delivers the sliced pineapples to the discharge opening 18 andwhen they register therewith the sliced pineapples drop by-gravity into thechutele and "may here be removed asdesired.

The disks formingthe turret may be cored out between the '-pocke ts 12 if desired to lighten the. structure as much as possible, but the uppermost plate is preferably left smooth as it forms a bottoni for the receivinghopper et,that is,--theffruit dropped into the hopper falls through-and rests uponthe uppermost plate ofthe' turret, but the fruit immediately drops intothepockets 12 when H The reason for 'employing the smooth surface should, therefore,.be obvious. 7

While certain features of the presentinvention are more or less specifically illustrated, I wish it understood that various changes in form and proportion maybe re sorted to within the scope of the appended jclaims, similarly :that; the matenials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may; dictate v or various uses may demand. r
